Question
____ is a dispersive effect within a spherical lens.
Answer
Chromatic aberration is a dispersive effect within a spherical lens.
Note: Depending on the thickness and curvature of the lens, there may be significant splitting of white light, which results in a rainbow halo around images. This phenomenon is corrected for in visual lenses like eyeglasses and car windows with special coatings that have different dispersive qualities from the lens itself.
Note: Here we see the purple fringing at the corners of the house, resulting from chromatic abberation.
